low cost and which may readily be assembled or disassembled to replace parts thereof.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings wherein a 16 preferred embodiment of one form of the present invention is clearly shown.

In the drawings: Fig. 1 is a front elevation of the signal device;

Fig. 2 is a view similar to Fig. 1 with the cover and frame removed, certain portions being shown in section for the sake of clearness;

Fig. 3 is a vertical section of the signal device; and i Figs. 4 and 5 are detail views of the connector plug.

Referring to the drawings, the signal device comprises a case 20 having a back wall 21, the outer or open edge of the case being provided with an inwardly extending flange 22. The case is divided into two compartments 23 and 24 by a partition 25, said partition having a depending flange 26 which lies adjacent to and engages the depressed portion 27 in the rear wall 21. The flange 26 and the depressed portion 27 are provided with apertures, in alignment when the parti tion is in position in the case. The shank portion 28 ofv a headed screw '29 extends through said aligned apertures and is upset over the rear wall as at 30 rigidly to secure the partition to said rear wall. This shank portion 28 extends beyond the rear surface of the wall and provides a mounting stud for the signal device. vided with two depending'ears 31 and 32, having screw threaded apertures, and lying in the plane of the casing flange 22. 7 r A translucent cover 33 having lens por- The partition is pro- Serial No. 165,516.

tions 34 and 35 of difierent type, closes the open end of the casing 20 so that the lense 34 provides a cover for compartment 23 and the lense 35 a cover for the compartment 24. A gasket .36 fits about the outer surface of thecover 33, said gasket being engaged by the inner edgeof a frame '37, which has aflange 38 adapted to fit about the casing 20. The frame is provided with two apertures aligning with the apertures in the cars 31 and 32 when the frame is in position on the casing, screws 39 extending through said apertures in the frameand screwing into the apertures in. the ears. 31 and 32 to hold said frame securely in position on the casing. Two openings40 "and 41 are provided in the 7 frame, the opening 40 fitting about the lense 34. while the opening 41 fits about the lense 35 of the cover 33. From this it; may be seen that the frame 37; holds the cover 33 in.70- position on the case, said frame in turn being secured to the case means of screws I which engage'the ears of partition 25.

Partition 25 has anaperture for receiving the base 45 of lamp 46, said partition sup-: porting the lamp so that it will be positioned in the compartment23 in direct alignment with the lens 34 of the cover. Adjacent the edge of the aperture which receives the lamp base 45, the partition-25 is provided with downwardly extending lug portions 47, slotted as at 47a, for receiving the laterally extending pins 476 with which electric lamps are usually provided.

Within the compartment 24 of the case 5 there is provided an angularbracket 48 secured to the rear Wall 21 of the casing by a stud 49, in a similar manner in which. the ear 26 of the partitionis secured to the .rear

wall of the case. The extending portion of the shank 49 provides additional mounting studs for the signal device. The bracket 48 like partition 25 is provided with extending lug portions SOforming a socket for receiving the base 51 of the 121-11113152- '95 In Fig. 3 it will be seen that the lamps 46 and 52 are so supported on the partitionand bracket respectively that their terminals 53 and 54 extend toward each otherwithin the compartment A clear glass lens 55 covice 7 ers an aperture 56 in the bottom wall of the casing, said glass being secured to the bottom of the casing by means of clamps 57 held in position by screws 58. This clear glass lens is adj aoent the lamp 52 so that the rays there of may project through said lens onto the license plate, mounted directly beneath the signal device.

An aperture surrounded by a flange 60 is provided in the rear wall 21 of the case. Said aperture receives the connector 61 which includes a metal sleeve 62 for receiving a denble terminal plug (not shown) having a latorally extending pin for engaging a bayonet slot 63. The sleeve 62 is joined by welding to the flange 60 and supports a non-conducting core (56 carrying spring contacts 64 and 65 insulated by a non-conducting strip 67. The ends 64a and 65a of these contacts provide terminals for receiving the twoterm-inals of the doubleterminal plug referred to. The contacts 64 and 65 engage lamp terminals 54 and 53 respectively when lamps 52 and 46 are assembled as shown.

The core 66 has anenla-rged head portion 68 provided with slots 69' for receiving the tongue portions 70 of the sleeve 62'. The tongues 70 are forced into the slots 68 and areto secure core 66 to the sleeve 62.

From the aforegoing description it may be seen that the lamps, if burned out, may be readily replaced by the removal of the screws 39' which permits removal of the cover and frame, thus making the lamps accessible.

" The connector core 66' may be removed from r the sleeve 62 after prying the tongues 70 away from the head 68 of the core 66.

The plane of the filament o-flamp 4L6 should be parallel withthe plane of lens- 3% for best illumination.

Substantially all parts of the device may be produced by the stamping process, thus maintaining the cost of production at a minimum.

\Vhilethe form of embodiment of the present invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming {vithin the scope of the claims which folhat, is claimed is as follows: 1. A tail and signal lamp comprising a casing, a partitionin the casing dividing it into upper and lower compartments, said partition'being provided with integral lamp socket holding means, ears on the front portion thereof, and a single broad-based, substantially triangular, car on the rear portion, a bolt passing through the latterear and the rear of the casing with its threaded portion outside of the casing and including means for rigidly fastening the partition and casing together.

2. The structure as set forth in claim 1 with a lamp supporting bracket in the lower comand means including a socket portion in the i casing between the bolts, for making detachable connection for the center contacts of lamps when located in said holders.

In testimony whereof I hereto affix my signature.
